The CSS-spec says:


    [ [ <size> | left | center | right ] [ <size> | top | center |
bottom ]? ]
    | [ [ center | [ left | right ] <size>? ] || [ center | [ top |
bottom ] <size>? ]
]

This would mean one can write:

-fx-background-position: left top;

or

-fx-background-position: top left;

but then the converter croaks:
